License Terms

Woman at Laptop

Each Wing Pro license grants one user the right to use Wing Pro, on as many machines as needed for their work.

Types of Licenses

  • Perpetual licenses are non-expiring licenses for one major release, such as Wing Pro 10, and all earlier releases.
  • Annual licenses work with any released version of Wing for one year, and then expire and stop working entirely unless they are renewed.

Non-Commercial Use variants of the above licenses are available for schools, unpaid individuals, publicly funded non-profits, and startup companies less than three years old.

Only Commercial Use licenses are transferable.

Most Wing Pro licenses are worldwide licenses that can be used in any country or region. Some discounted licenses are designated at the time of sale as geographically restricted to a specific country or region. These licenses are invalid and will not work in other countries or regions.

Support and Upgrades

All licenses include one year of email support and access to newly released version of Wing Pro.

For Perpetual licenses, access to Support+Upgrades may extended, at a cost of US$ 99/year for Commercial Use licenses or US$ 44/year for Non-Commercial Use licenses.

For Annual licenses, all renewals include Support+Upgrades.

Non-Commercial Use licenses may be upgraded to Commercial Use by paying the price difference between the original and upgraded license.

Please see Support+Upgrades for details and use our online store for all types of renewals and upgrades.
